4.1 Confirming the I/O Number Allocations and First Word Number

4.1.1 Occupied I/O Area and I/O Allocations

In the FP7, analog input data is allocated to the external input relay area and processed.
An analog input signal into a single channel is handled by 16 X-contact points.
The following table shows the I/O allocation of analog input data.

* A/D conversion data within the set scale
applies if scale conversion is set.
ON with disconnection detected and OFF
with disconnection restored
(valid for 1 to 5 V and 4 to 20 mA ranges
only)
Turns ON when the value exceeds the set
upper limit.
Turns ON when the value drops below the
set lower limit.
ON when the upper limit/lower limit
comparison function is executed.
Do not use.
ON when the max./min. hold function is
executed.
Do not use.
ON when the buffer function is executed.
ON when buffering starts after the trigger is
accepted.
OFF when the number of buffer data items is
reached.
ON when the shared memory has become
accessible after completion of buffering
OFF on completion of buffer data reading.
ON when the number of buffer data items
before triggering has reached the set value.
OFF on completion of buffer data reading.
